Pomalidomide Plus Anti-CD20 Antibody and Prednisone in Frontline Indolent B-Cell Lymphoma

A Phase II Study of Pomalidomide Combined with Anti-CD20 Monoclonal Antibody and Prednisone in Frontline Indolent B-Cell Lymphoma Objective: This prospective, single-arm, Phase II trial aims to evaluate the efficacy and safety of first-line pomalidomide plus anti-CD20 antibody and prednisone in patients with indolent B-cell lymphoma. Study Population: Approximately 30 adult patients (age ≥18 years) will be enrolled. Eligible histologies include follicular lymphoma (FL), CD20-positive marginal zone lymphoma (MZL: extranodal MALT, splenic SMZL, nodal NMZL), indolent mantle cell lymphoma (MCL), chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), and lymphoplasmacytic lymphoma/Waldenström macroglobulinemia. Patients must be treatment-naïve, have an indication for systemic therapy, ECOG performance status 0-2, and adequate bone marrow reserve (ANC ≥1.5×10⁹/L, platelets ≥75×10⁹/L, hemoglobin ≥9.0 g/dL; lower thresholds permitted if marrow/spleen involvement, per investigator discretion). Adequate organ function is required: bilirubin ≤2×ULN, ALT/AST ≤2.5×ULN, and creatinine clearance \>30 mL/min. Life expectancy must be ≥3 months, and written informed consent is mandatory. Exclusion Criteria: Patients are excluded if they have another malignancy within 5 years (unless curatively treated without recurrence), CNS lymphoma involvement, transformation to high-grade lymphoma, uncontrolled infection, severe comorbidities affecting study participation, significant non-lymphoma-related organ dysfunction (ALT/AST \>3×ULN, bilirubin \>2×ULN, creatinine \>1.5×ULN), active CNS dysfunction, major surgery within 30 days, pregnancy or lactation, lack of contraception in women of childbearing potential, known drug hypersensitivity, or any condition deemed unsuitable by the investigator. Treatment Regimen: Induction consists of six 28-day cycles. Anti-CD20 antibody is administered at 375 mg/m² weekly during Cycle 1 and on Day 1 of Cycles 2-6. Pomalidomide is given at 4 mg/day on Days 2-22 of Cycles 1-6. Prednisone is administered at 100 mg/day on Days 1-5 of Cycles 1-6. Maintenance therapy continues for 2 years with pomalidomide 4 mg/day on Days 1-14 and anti-CD20 antibody 375 mg/m² on Day 1 every 8 weeks. Endpoints: The primary endpoint is overall response rate (ORR). Secondary endpoints include complete response rate (CR), progression-free survival (PFS), overall survival (OS), and safety (hematologic and non-hematologic adverse events). Statistical Methods: Continuous variables will be summarized with descriptive statistics; categorical variables with frequencies and percentages. Time-to-event endpoints (PFS, OS, and duration of response) will be analyzed using the Kaplan-Meier method, reporting medians, quartiles, and 90% confidence intervals, along with event and censoring counts. ORR will be tested statistically and reported with a 90% confidence interval. Timeline: The study is expected to begin in January 2026, complete enrollment by December 2026, and conclude by December 2027. The total planned sample size is 30 patients.

NKX019, Intravenous Allogeneic Chimeric Antigen Receptor Natural Killer Cells (CAR NK), in Adults With B-cell Cancers

This is a single arm, open-label, multi-center, Phase 1 study to determine the safety and tolerability of an experimental therapy called NKX019 (allogeneic CAR NK cells targeting CD19) in patients with relapsed/refractory non-Hodgkin lymphoma (NHL), chronic lymphocytic leukemia (CLL) or B cell acute lymphoblastic leukemia (B-ALL)

Efficacy and Safety of Lisaftoclax (APG-2575) Monotherapy in Patients With Indolent Lymphoma

This is a multicenter, prospective, single-arm phase II study designed to evaluate the safety and efficacy of lisaftoclax (APG-2575), an oral selective BCL-2 inhibitor, in patients with indolent B-cell lymphomas. The study will enroll adult patients with chronic lymphocytic leukemia (CLL), Waldenström macroglobulinemia (WM), or marginal zone lymphoma (MZL) who are either treatment-naïve but considered ineligible for Bruton tyrosine kinase (BTK) inhibitor therapy due to significant comorbidities, or who are intolerant to prior BTK inhibitor treatment. Eligible patients will receive oral lisaftoclax once daily with a dose ramp-up to a target dose of 600 mg in 28-day cycles. Treatment will continue until disease progression, unacceptable toxicity, withdrawal of consent, or completion of the planned treatment period. The primary objective is to evaluate the safety and tolerability of lisaftoclax monotherapy, while secondary objectives include assessment of antitumor activity, including overall response rate (ORR), complete response (CR) rate, minimal residual disease (MRD) negativity, progression-free survival (PFS), duration of response (DOR), and overall survival (OS). Quality of life will also be assessed using the EORTC QLQ-C30 questionnaire.

Pomalidomide Combined With Obinutuzumab in the Treatment of Patients With Relapsed/Refractory Indolent Lymphoma

To explore the maximum tolerated dose (MTD) of pomalidomide in combination with obinutuzumab in patients with relapsed/refractory indolent lymphomas (including follicular lymphoma, marginal zone lymphoma, and chronic lymphocytic leukemia/small lymphocytic lymphoma) treated with the pomalidomide plus obinutuzumab combination regimen, and to determine the recommended phase II dose (RP2D); concurrently evaluating the efficacy and safety of pomalidomide combined with obinutuzumab in patients with relapsed/refractory indolent lymphomas.

A Phase 2 Study to Evaluate the Safety and Efficacy of Pacritinib in Relapsed or Refractory Waldenström Macroglobulinemia

This study is being done to examine the safety and effectiveness of pacritinib as a possible treatment for participants with Waldenström macroglobulinemia (WM). The name of the study drug involved in this study is: -Pacritinib (a type of kinase inhibitor)
